Yes I did, many times. Version 3.3.3.3 syncs to block 9165, 3.3.4.3 to 1025, 3.3.4.4 to 9020.
When version 3.3.4.3 came out, I wanted to try it and wanted to see if sync is working properly. I deleted all data, started wallet and since then it did not work. I left the wallet for more than 24 hours version 3.3.4.3 open and nothing. Today I compiled new version 3.3.4.4, still does not work. Running peerinfo I can see than all peers do have version 3.3.3.3.
If new versions are broken, why are broken version posted untested? Is there anyone who can resync completly with 3.3.4.4?
I'm fully synced with 3.3.4.4
Could you try to delete all data except your wallet and resync?
these are what I'm connected to now, after deleting everything.

those two that are running 3.3.3.3 are messing with the network.
if you compile yourself, edit
version.h, change min proto version so its the same as the network protocol version. Then recompile. This will not allow older version to connect to you
